FIELD OF THE INVENTION

The present invention relates to antibodies directed to epitopes of Human Immunodeficiency Virus (“HIV”). The present invention further relates to the preparation and use of broadly neutralizing antibodies directed to the HIV gp120 envelope protein for the prevention and treatment of HIV infection.

BACKGROUND OF THE INVENTION

HIV causes Acquired Immunodeficiency Syndrome (“AIDS”). The immune response to HIV infection in long-term non-progressors suggests that specific viral immunity may limit infection and the symptoms of disease. Some HIV infected individuals show broadly neutralizing IgG antibodies in their serum; little is known regarding the specificity and activity of these antibodies, despite their potential importance in designing effective vaccines, and no single characteristic has of yet been correlated with protective immunity. In animal models, passive transfer of neutralizing antibodies can contribute to protection against virus challenge. Neutralizing antibody responses also can be developed in HIV-infected individuals but the detailed composition of the serologic response is yet to be fully uncovered.

A number of immunologic abnormalities have been described in AIDS. These include, but are not limited to, abnormalities in B-cell function, abnormal antibody response, defective monocyte cell function, impaired cytokine production, depressed natural killer and cytotoxic cell function, defective ability of lymphocytes to recognize and respond to soluble antigens, and the depletion of the T4 helper/inducer lymphocyte population.

The amino acid and RNA sequences encoding HIV env from a number of HIV strains are known (Modrow, S. et al., J. Virology 61(2): 570 (1987)). The HIV virion is covered by a membrane or envelope derived from the outer membrane of host cells. This membrane contains a population of envelope glycoproteins (gp 160) anchored in the membrane bilayer at their carboxyl terminal region. Each glycoprotein contains two segments: the N-terminal segment, and the C-terminal segment. The N-terminal segment, called gp120 by virtue of its relative molecular weight of about 120 kD, protrudes into the aqueous environment surrounding the virion. The C-terminal segment, called gp41, spans the membrane. The N-terminal gp120 and the C-terminal gp41 are covalently linked by a peptide bond that is particularly susceptible to proteolytic cleavage. See European Patent Application Publication No. 0 335 635 to McCune et al and the references cited therein, each incorporated herein by reference in its entirety.

Several approaches to an AIDS vaccine have been proposed, including, but not limited to, inactivated and attenuated virus vaccines, subunit vaccines from virus-infected cells, recombinantly produced viral antigens, vaccines based on synthetic peptides, anti-idiotypic vaccines, and viral carrier-based vaccines. An additional approach to HIV therapeutic and prophylactic treatment includes making highly potent, broadly neutralizing monoclonal antibodies. Multiple studies have reported cloning and making monoclonal antibodies by various techniques for targeting the CD4 binding site as well as other parts of the virion spike and for neutralizing HIV. Generally, these techniques involve self-fusion or phage display techniques. Typically, in making HIV neutralizing antibodies using phage display techniques, random combinations of heavy and light chains are combined and a random pair is selected. Studies have reported a limited number of monoclonal antibodies, such as, for example, the phage display antibody b12, that are broadly highly potent, and broadly neutralizing (meaning antibodies that can neutralize multiple strains of HIV in sera) against HIV. The monoclonal antibody b12 is a broadly neutralizing antibody which has been reported to prevent HIV infection in macaques. Another broadly neutralizing antibody includes 2G12, which, atypically, has a structure which has yet to be seen in any other antibody with three combining sites. VRC01 is recently discovered broadly neutralizing antibody that targets the CD4 binding site (CD4bs) on the HIV spike. VRC01 was isolated by purifying single B cells that bind to a soluble, biotin labeled, stabilized, and re-surfaced core fragment of HIV gp120 (X. Wu et al., Science 329, 856 (Aug. 13, 2010)). Although successful, the isolation was inefficient, producing only 3 closely related HIV-binding antibodies from 25 million peripheral blood mononuclear cells from one individual. Like other anti-HIV antibodies obtained by the single cell antigen capture method, VRC01-3 showed very high levels of somatic mutations that were essential for potency and breadth. This high frequency of mutation is a potential impediment to antibody cloning because the mutated sequences may no longer be complementary to the primers used for cloning.

Some studies have reported that certain patients develop antibodies to HIV that are broadly neutralizing. Studies have reported that antibodies can be protective against initial HIV infection in passive transfer experiments in non-human primates and can modulate viral load during infection. See, for example, Mascola, 2000; Shibata, 1999; Veazey, 2003; Parren, 2001; Mascola, 1999; Trkola, 2005; Wei, 2003; Frost, 2005; Burton, 2004; Mascola, 2007; Karlsson Hedestam, 2008; McMichael, 2006; Zolla-Pazner, 2004.

The term “antibody” (Ab) as used herein includes monoclonal antibodies, polyclonal antibodies, multispecific antibodies (for example, bispecific antibodies and polyreactive antibodies), and antibody fragments. Thus, the term “antibody” as used in any context within this specification is meant to include, but not be limited to, any specific binding member, immunoglobulin class and/or isotype (e.g., IgG1, IgG2, IgG3, IgG4, IgM, IgA, IgD, IgE and IgM); and biologically relevant fragment or specific binding member thereof, including but not limited to Fab, F(ab′)2, Fv, and scFv (single chain or related entity). It is understood in the art that an antibody is a glycoprotein comprising at least two heavy (H) chains and two light (L) chains inter-connected by disulfide bonds, or an antigen binding portion thereof. A heavy chain is comprised of a heavy chain variable region (VH) and a heavy chain constant region (CH1, CH2 and CH3). A light chain is comprised of a light chain variable region (VL) and a light chain constant region (CL). The variable regions of both the heavy and light chains comprise framework regions (FWR) and complementarity determining regions (CDR). The four FWR regions are relatively conserved while CDR regions (CDR1, CDR2 and CDR3) represent hypervariable regions and are arranged from NH2 terminus to the COOH terminus as follows: FWR1, CDR1, FWR2, CDR2, FWR3, CDR3, FWR4. The variable regions of the heavy and light chains contain a binding domain that interacts with an antigen while, depending of the isotype, the constant region(s) may mediate the binding of the immunoglobulin to host tissues or factors.

Also included in the definition of “antibody” as used herein are chimeric antibodies, humanized antibodies, and recombinant antibodies, human antibodies generated from a transgenic non-human animal, as well as antibodies selected from libraries using enrichment technologies available to the artisan.

The term “variable” refers to the fact that certain segments of the variable (V) domains differ extensively in sequence among antibodies. The V domain mediates antigen binding and defines specificity of a particular antibody for its particular antigen. However, the variability is not evenly distributed across the 110-amino acid span of the variable regions. Instead, the V regions consist of relatively invariant stretches called framework regions (FRs) of 15-30 amino acids separated by shorter regions of extreme variability called “hypervariable regions” that are each 9-12 amino acids long. The variable regions of native heavy and light chains each comprise four FRs, largely adopting a beta sheet configuration, connected by three hypervariable regions, which form loops connecting, and in some cases forming part of, the beta sheet structure. The hypervariable regions in each chain are held together in close proximity by the FRs and, with the hypervariable regions from the other chain, contribute to the formation of the antigen-binding site of antibodies (see, for example, Kabat et al., Sequences of Proteins of Immunological Interest, 5th Ed. Public Health Service, National Institutes of Health, Bethesda, Md. (1991)).

The term “hypervariable region” as used herein refers to the amino acid residues of an antibody that are responsible for antigen binding. The hypervariable region generally comprises amino acid residues from a “complementarity determining region” (“CDR”).

The term “monoclonal antibody” as used herein refers to an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts. The term “polyclonal antibody” refers to preparations that include different antibodies directed against different determinants (“epitopes”).

The monoclonal antibodies herein include “chimeric” antibodies in which a portion of the heavy and/or light chain is identical with, or homologous to, corresponding sequences in antibodies derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is identical with, or homologous to, corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, so long as they exhibit the desired biological activity (see, for example, U.S. Pat. No. 4,816,567; and Morrison et al., Proc. Natl. Acad. Sci. USA, 81:6851-6855 (1984)). The described invention provides variable region antigen-binding sequences derived from human antibodies. Accordingly, chimeric antibodies of primary interest herein include antibodies having one or more human antigen binding sequences (for example, CDRs) and containing one or more sequences derived from a non-human antibody, for example, an FR or C region sequence. In addition, chimeric antibodies included herein are those comprising a human variable region antigen binding sequence of one antibody class or subclass and another sequence, for example, FR or C region sequence, derived from another antibody class or subclass.

A “humanized antibody” generally is considered to be a human antibody that has one or more amino acid residues introduced into it from a source that is non-human. These non-human amino acid residues often are referred to as “import” residues, which typically are taken from an “import” variable region. Humanization may be performed following the method of Winter and co-workers (see, for example, Jones et al., Nature, 321:522-525 (1986); Reichmann et al., Nature, 332:323-327 (1988); Verhoeyen et al., Science, 239:1534-1536 (1988)), by substituting import hypervariable region sequences for the corresponding sequences of a human antibody. Accordingly, such “humanized” antibodies are chimeric antibodies (see, for example, U.S. Pat. No. 4,816,567), wherein substantially less than an intact human variable region has been substituted by the corresponding sequence from a non-human species.

An “antibody fragment” comprises a portion of an intact antibody, such as the antigen binding or variable region of the intact antibody. Examples of antibody fragments include, but are not limited to, Fab, Fab′, F(ab′)2, and Fv fragments; diabodies; linear antibodies (see, for example, U.S. Pat. No. 5,641,870; Zapata et al., Protein Eng. 8(10): 1057-1062 [1995]); single-chain antibody molecules; and multispecific antibodies formed from antibody fragments.

“Fv” is the minimum antibody fragment that contains a complete antigen-recognition and antigen-binding site. This fragment contains a dimer of one heavy- and one light-chain variable region domain in tight, non-covalent association. From the folding of these two domains emanate six hypervariable loops (three loops each from the H and L chain) that contribute the amino acid residues for antigen binding and confer antigen binding specificity to the antibody. However, even a single variable region (or half of an Fv comprising only three CDRs specific for an antigen) has the ability to recognize and bind antigen, although at a lower affinity than the entire binding site.

“Single-chain Fv” (“sFv” or “scFv”) are antibody fragments that comprise the VH and VL antibody domains connected into a single polypeptide chain. The sFv polypeptide can further comprise a polypeptide linker between the VH and VL domains that enables the sFv to form the desired structure for antigen binding. For a review of sFv, see, for example, Pluckthun in The Pharmacology of Monoclonal Antibodies, vol. 113, Rosenburg and Moore eds., Springer-Verlag, New York, pp. 269-315 (1994); Borrebaeck 1995, infra.

The term “diabodies” refers to small antibody fragments prepared by constructing sFv fragments with short linkers (about 5-10 residues) between the VH and VL domains such that inter-chain but not intra-chain pairing of the V domains is achieved, resulting in a bivalent fragment, i.e., fragment having two antigen-binding sites. Bispecific diabodies are heterodimers of two “crossover” sFv fragments in which the VH and VL domains of the two antibodies are present on different polypeptide chains. Diabodies are described more fully in, for example, EP 404,097; WO 93/11161; and Hollinger et al., Proc. Natl. Acad. Sci. USA, 90:6444-6448 (1993).

Domain antibodies (dAbs), which can be produced in fully human form, are the smallest known antigen-binding fragments of antibodies, ranging from about 11 kDa to about 15 kDa. dAbs are the robust variable regions of the heavy and light chains of immunoglobulins (VH and VL, respectively). They are highly expressed in microbial cell culture, show favorable biophysical properties including, for example, but not limited to, solubility and temperature stability, and are well suited to selection and affinity maturation by in vitro selection systems such as, for example, phage display. dAbs are bioactive as monomers and, owing to their small size and inherent stability, can be formatted into larger molecules to create drugs with prolonged serum half-lives or other pharmacological activities. Examples of this technology have been described in, for example, WO9425591 for antibodies derived from Camelidae heavy chain Ig, as well in US20030130496 describing the isolation of single domain fully human antibodies from phage libraries.

Fv and sFv are the only species with intact combining sites that are devoid of constant regions. Thus, they are suitable for reduced nonspecific binding during in vivo use. sFv fusion proteins can be constructed to yield fusion of an effector protein at either the amino or the carboxy terminus of an sFv. See, for example, Antibody Engineering, ed. Borrebaeck, supra. The antibody fragment also can be a “linear antibody”, for example, as described in U.S. Pat. No. 5,641,870 for example. Such linear antibody fragments can be monospecific or bispecific.

In certain embodiments, antibodies of the described invention are bispecific or multi-specific. Bispecific antibodies are antibodies that have binding specificities for at least two different epitopes. Exemplary bispecific antibodies can bind to two different epitopes of a single antigen. Other such antibodies can combine a first antigen binding site with a binding site for a second antigen. Alternatively, an anti-HIV arm can be combined with an arm that binds to a triggering molecule on a leukocyte, such as a T-cell receptor molecule (for example, CD3), or Fc receptors for IgG (Fc gamma R), such as Fc gamma RI (CD64), Fc gamma RII (CD32) and Fc gamma RIII (CD16), so as to focus and localize cellular defense mechanisms to the infected cell. Bispecific antibodies also can be used to localize cytotoxic agents to infected cells. Bispecific antibodies can be prepared as full length antibodies or antibody fragments (for example, F(ab′)2 bispecific antibodies). For example, WO 96/16673 describes a bispecific anti-ErbB2/anti-Fc gamma RIII antibody and U.S. Pat. No. 5,837,234 discloses a bispecific anti-ErbB2/anti-Fc gamma RI antibody. For example, a bispecific anti-ErbB2/Fc alpha antibody is reported in WO98/02463; U.S. Pat. No. 5,821,337 teaches a bispecific anti-ErbB2/anti-CD3 antibody. See also, for example, Mouquet et al., Polyreactivity Increases The Apparent Affinity Of Anti-HIV Antibodies By Heteroligation. NATURE. 467, 591-5 (2010).

Methods for making bispecific antibodies are known in the art. Traditional production of full length bispecific antibodies is based on the co-expression of two immunoglobulin heavy chain-light chain pairs, where the two chains have different specificities (see, for example, Millstein et al., Nature, 305:537-539 (1983)). Similar procedures are disclosed in, for example, WO 93/08829, Traunecker et al., EMBO J., 10:3655-3659 (1991) and see also; Mouquet et al., Polyreactivity Increases The Apparent Affinity Of Anti-HIV Antibodies By Heteroligation. NATURE. 467, 591-5 (2010).

Alternatively, antibody variable regions with the desired binding specificities (antibody-antigen combining sites) are fused to immunoglobulin constant domain sequences. The fusion is with an Ig heavy chain constant domain, comprising at least part of the hinge, CH2, and CH3 regions. According to some embodiments, the first heavy-chain constant region (CH1) containing the site necessary for light chain bonding, is present in at least one of the fusions. DNAs encoding the immunoglobulin heavy chain fusions and, if desired, the immunoglobulin light chain, are inserted into separate expression vectors, and are co-transfected into a suitable host cell. This provides for greater flexibility in adjusting the mutual proportions of the three polypeptide fragments in embodiments when unequal ratios of the three polypeptide chains used in the construction provide the optimum yield of the desired bispecific antibody. It is, however, possible to insert the coding sequences for two or all three polypeptide chains into a single expression vector when the expression of at least two polypeptide chains in equal ratios results in high yields or when the ratios have no significant affect on the yield of the desired chain combination.

Techniques for generating bispecific antibodies from antibody fragments also have been described in the literature. For example, bispecific antibodies can be prepared using chemical linkage. For example, Brennan et al., Science, 229: 81 (1985) describe a procedure wherein intact antibodies are proteolytically cleaved to generate F(ab′)2 fragments. These fragments are reduced in the presence of the dithiol complexing agent, sodium arsenite, to stabilize vicinal dithiols and prevent intermolecular disulfide formation. The Fab′ fragments generated then are converted to thionitrobenzoate (TNB) derivatives. One of the Fab′-TNB derivatives then is reconverted to the Fab′-thiol by reduction with mercaptoethylamine and is mixed with an equimolar amount of the other Fab′-TNB derivative to form the bispecific antibody. The bispecific antibodies produced can be used as agents for the selective immobilization of enzymes.

Other modifications of the antibody are contemplated herein. For example, the antibody can be linked to one of a variety of nonproteinaceous polymers, for example, polyethylene glycol, polypropylene glycol, polyoxyalkylenes, or copolymers of polyethylene glycol and polypropylene glycol. The antibody also can be entrapped in microcapsules prepared, for example, by coacervation techniques or by interfacial polymerization (for example, hydroxymethylcellulose or gelatin-microcapsules and poly-(methylmethacylate)microcapsules, respectively), in colloidal drug delivery systems (for example, liposomes, albumin microspheres, microemulsions, nano-particles and nanocapsules), or in macroemulsions. Such techniques are disclosed in, for example, Remington's Pharmaceutical Sciences, 16th edition, Oslo, A., Ed., (1980).

Typically, the antibodies of the described invention are produced recombinantly, using vectors and methods available in the art. Human antibodies also can be generated by in vitro activated B cells (see, for example, U.S. Pat. Nos. 5,567,610 and 5,229,275). General methods in molecular genetics and genetic engineering useful in the present invention are described in the current editions of Molecular Cloning: A Laboratory Manual (Sambrook, et al., 1989, Cold Spring Harbor Laboratory Press), Gene Expression Technology (Methods in Enzymology, Vol. 185, edited by D. Goeddel, 1991. Academic Press, San Diego, Calif.), “Guide to Protein Purification” in Methods in Enzymology (M. P. Deutshcer, ed., (1990) Academic Press, Inc.); PCR Protocols: A Guide to Methods and Applications (Innis, et al. 1990. Academic Press, San Diego, Calif.), Culture of Animal Cells: A Manual of Basic Technique, 2nd Ed. (R. I. Freshney. 1987. Liss, Inc. New York, N.Y.), and Gene Transfer and Expression Protocols, pp. 109-128, ed. E. J. Murray, The Humana Press Inc., Clifton, N.J.). Reagents, cloning vectors, and kits for genetic manipulation are available from commercial vendors such as BioRad, Stratagene, Invitrogen, ClonTech and Sigma-Aldrich Co.

Human antibodies also can be produced in transgenic animals (for example, mice) that are capable of producing a full repertoire of human antibodies in the absence of endogenous immunoglobulin production. For example, it has been described that the homozygous deletion of the antibody heavy-chain joining region (JH) gene in chimeric and germ-line mutant mice results in complete inhibition of endogenous antibody production. Transfer of the human germ-line immunoglobulin gene array into such germ-line mutant mice results in the production of human antibodies upon antigen challenge. See, for example, Jakobovits et al., Proc. Natl. Acad. Sci. USA, 90:2551 (1993); Jakobovits et al., Nature, 362:255-258 (1993); Bruggemann et al., Year in Immuno., 7:33 (1993); U.S. Pat. Nos. 5,545,806, 5,569,825, 5,591,669 (all of GenPharm); U.S. Pat. No. 5,545,807; and WO 97/17852. Such animals can be genetically engineered to produce human antibodies comprising a polypeptide of the described invention.

Various techniques have been developed for the production of antibody fragments. Traditionally, these fragments were derived via proteolytic digestion of intact antibodies (see, for example, Morimoto et al., Journal of Biochemical and Biophysical Methods 24:107-117 (1992); and Brennan et al., Science, 229:81 (1985)). However, these fragments can now be produced directly by recombinant host cells. Fab, Fv and ScFv antibody fragments can all be expressed in and secreted from E. coli, thus allowing the facile production of large amounts of these fragments. Fab′-SH fragments can be directly recovered from E. coli and chemically coupled to form F(ab′)2 fragments (see, for example, Carter et al., Bio/Technology 10:163-167 (1992)). According to another approach, F(ab′)2 fragments can be isolated directly from recombinant host cell culture. Fab and F(ab′)2 fragment with increased in vivo half-life comprising a salvage receptor binding epitope residues are described in U.S. Pat. No. 5,869,046. Other techniques for the production of antibody fragments will be apparent to the skilled practitioner.

Other techniques that are known in the art for the selection of antibody fragments from libraries using enrichment technologies, including but not limited to phage display, ribosome display (Hanes and Pluckthun, 1997, Proc. Nat. Acad. Sci. 94: 4937-4942), bacterial display (Georgiou, et al., 1997, Nature Biotechnology 15: 29-34) and/or yeast display (Kieke, et al., 1997, Protein Engineering 10: 1303-1310) may be utilized as alternatives to previously discussed technologies to select single chain antibodies. Single-chain antibodies are selected from a library of single chain antibodies produced directly utilizing filamentous phage technology. Phage display technology is known in the art (e.g., see technology from Cambridge Antibody Technology (CAT)) as disclosed in U.S. Pat. Nos. 5,565,332; 5,733,743; 5,871,907; 5,872,215; 5,885,793; 5,962,255; 6,140,471; 6,225,447; 6,291650; 6,492,160; 6,521,404; 6,544,731; 6,555,313; 6,582,915; 6,593, 081, as well as other U.S. family members, or applications which rely on priority filing GB 9206318, filed 24 May 1992; see also Vaughn, et al. 1996, Nature Biotechnology 14: 309-314). Single chain antibodies may also be designed and constructed using available recombinant DNA technology, such as a DNA amplification method (e.g., PCR), or possibly by using a respective hybridoma cDNA as a template.

Variant antibodies also are included within the scope of the invention. Thus, variants of the sequences recited in the application also are included within the scope of the invention. Further variants of the antibody sequences having improved affinity can be obtained using methods known in the art and are included within the scope of the invention. For example, amino acid substitutions can be used to obtain antibodies with further improved affinity. Alternatively, codon optimization of the nucleotide sequence can be used to improve the efficiency of translation in expression systems for the production of the antibody.

Such variant antibody sequences will share 70% or more (i.e., 80%, 85%, 90%, 95%, 97%, 98%, 99% or greater) sequence identity with the sequences recited in the application. Such sequence identity is calculated with regard to the full length of the reference sequence (i.e., the sequence recited in the application). Percentage identity, as referred to herein, is as determined using BLAST version 2.1.3 using the default parameters specified by the NCBI (the National Center for Biotechnology Information; http://www.ncbi.nlm.nih.gov/) [Blosum 62 matrix; gap open penalty=11 and gap extension penalty=1]. For example, peptide sequences are provided by this invention that comprise at least about 5, 10, 15, 20, 30, 40, 50, 75, 100, 150, or more contiguous peptides of one or more of the sequences disclosed herein as well as all intermediate lengths there between. As used herein, the term “intermediate lengths” is meant to describe any length between the quoted values, such as 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, etc.; 21, 22, 23, etc.; 30, 31, 32, etc.; 50, 51, 52, 53, etc.; 100, 101, 102, 103, etc.; 150, 151, 152, 153, etc.

The present invention provides for antibodies, either alone or in combination with other antibodies, such as, but not limited to, VRC01 and PG9, that have broad neutralizing activity in serum.

According to another embodiment, the present invention provides methods for the preparation and administration of an HIV antibody composition that is suitable for administration to a human or non-human primate patient having HIV infection, or at risk of HIV infection, in an amount and according to a schedule sufficient to induce a protective immune response against HIV, or reduction of the HIV virus, in a human.

According to another embodiment, the present invention provides a vaccine comprising at least one antibody of the invention and a pharmaceutically acceptable carrier. According to one embodiment, the vaccine is a vaccine comprising at least one antibody described herein and a pharmaceutically acceptable carrier. The vaccine can include a plurality of the antibodies having the characteristics described herein in any combination and can further include antibodies neutralizing to HIV as are known in the art.

It is to be understood that compositions can be a single or a combination of antibodies disclosed herein, which can be the same or different, in order to prophylactically or therapeutically treat the progression of various subtypes of HIV infection after vaccination. Such combinations can be selected according to the desired immunity. When an antibody is administered to an animal or a human, it can be combined with one or more pharmaceutically acceptable carriers, excipients or adjuvants as are known to one of ordinary skilled in the art. The composition can further include broadly neutralizing antibodies known in the art, including but not limited to, VRC01, PG9 and b12.

Further, with respect to determining the effective level in a patient for treatment of HIV, in particular, suitable animal models are available and have been widely implemented for evaluating the in vivo efficacy against HIV of various gene therapy protocols (Sarver et al. (1993b), supra). These models include mice, monkeys and cats. Even though these animals are not naturally susceptible to HIV disease, chimeric mice models (for example, SCID, bg/nu/xid, NOD/SCID, SCID-hu, immunocompetent SCID-hu, bone marrow-ablated BALB/c) reconstituted with human peripheral blood mononuclear cells (PBMCs), lymph nodes, fetal liver/thymus or other tissues can be infected with lentiviral vector or HIV, and employed as models for HIV pathogenesis. Similarly, the simian immune deficiency virus (SIV)/monkey model can be employed, as can the feline immune deficiency virus (FIV)/cat model. The pharmaceutical composition can contain other pharmaceuticals, in conjunction with a vector according to the invention, when used to therapeutically treat AIDS. These other pharmaceuticals can be used in their traditional fashion (i.e., as antiviral agents to treat HIV infection). Examples of HIV agents include without limitation non-nucleoside reverse transcriptase inhibitors, protease inhibitors, entry or fusion inhibitors and integrase inhibitors

According to another embodiment, the present invention provides an antibody-based pharmaceutical composition comprising an effective amount of an isolated HIV antibody, or an affinity matured version, which provides a prophylactic or therapeutic treatment choice to reduce infection of the HIV virus. The antibody-based pharmaceutical composition of the present invention may be formulated by any number of strategies known in the art (e.g., see McGoff and Scher, 2000, Solution Formulation of Proteins/Peptides: In McNally, E. J., ed. Protein Formulation and Delivery. New York, N.Y.: Marcel Dekker; pp. 139-158; Akers and Defilippis, 2000, Peptides and Proteins as Parenteral Solutions. In: Pharmaceutical Formulation Development of Peptides and Proteins. Philadelphia, Pa.: Talyor and Francis; pp. 145-177; Akers, et al., 2002, Pharm. Biotechnol. 14:47-127). A pharmaceutically acceptable composition suitable for patient administration will contain an effective amount of the antibody in a formulation which both retains biological activity while also promoting maximal stability during storage within an acceptable temperature range. The pharmaceutical compositions can also include, depending on the formulation desired, pharmaceutically acceptable diluents, pharmaceutically acceptable carriers and/or pharmaceutically acceptable excipients, or any such vehicle commonly used to formulate pharmaceutical compositions for animal or human administration. The diluent is selected so as not to affect the biological activity of the combination. Examples of such diluents are distilled water, physiological phosphate-buffered saline, Ringer's solutions, dextrose solution, and Hank's solution. The amount of an excipient that is useful in the pharmaceutical composition or formulation of this invention is an amount that serves to uniformly distribute the antibody throughout the composition so that it can be uniformly dispersed when it is to be delivered to a subject in need thereof. It may serve to dilute the antibody to a concentration which provides the desired beneficial palliative or curative results while at the same time minimizing any adverse side effects that might occur from too high a concentration. It may also have a preservative effect. Thus, for the antibody having a high physiological activity, more of the excipient will be employed. On the other hand, for any active ingredient(s) that exhibit a lower physiological activity, a lesser quantity of the excipient will be employed.

The above described antibodies and antibody compositions or vaccine compositions, comprising at least one or a combination of the antibodies described herein, can be administered for the prophylactic and therapeutic treatment of HIV viral infection.

The present invention also relates to isolated polypeptides comprising the amino acid sequences of the light chains and heavy chains listed in Tables A, B and FIGS. 10 A-C; the consensus sequences for the heavy and light chains of SEQ ID NOs: 1 and 2; and insertion sequences SEQ ID NOs: 3 and 4.

In other related embodiments, the invention provides polypeptide variants that encode the amino acid sequences of the HIV antibodies listed in Tables A, B and FIG. 10 A-C; the consensus sequences for the heavy and light chains of SEQ ID NOs: 1 and 2; and insertion sequences SEQ ID NOs: 3 and 4. These polypeptide variants have at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99%, or greater, sequence identity compared to a polypeptide sequence of this invention, as determined using the methods described herein, (for example, BLAST analysis using standard parameters). One skilled in this art will recognize that these values can be appropriately adjusted to determine corresponding identity of proteins encoded by taking into amino acid similarity and the like.

The term “polypeptide” is used in its conventional meaning, i.e., as a sequence of amino acids. The polypeptides are not limited to a specific length of the product. Peptides, oligopeptides, and proteins are included within the definition of polypeptide, and such terms can be used interchangeably herein unless specifically indicated otherwise. This term also includes post-expression modifications of the polypeptide, for example, glycosylations, acetylations, phosphorylations and the like, as well as other modifications known in the art, both naturally occurring and non-naturally occurring. A polypeptide can be an entire protein, or a subsequence thereof. Particular polypeptides of interest in the context of this invention are amino acid subsequences comprising CDRs, VH and VL, being capable of binding an antigen or HIV-infected cell.

A polypeptide “variant,” as the term is used herein, is a polypeptide that typically differs from a polypeptide specifically disclosed herein in one or more substitutions, deletions, additions and/or insertions. Such variants can be naturally occurring or can be synthetically generated, for example, by modifying one or more of the above polypeptide sequences of the invention and evaluating one or more biological activities of the polypeptide as described herein and/or using any of a number of techniques well known in the art.

For example, certain amino acids can be substituted for other amino acids in a protein structure without appreciable loss of its ability to bind other polypeptides (for example, antigens) or cells. Since it is the binding capacity and nature of a protein that defines that protein's biological functional activity, certain amino acid sequence substitutions can be made in a protein sequence, and, accordingly, its underlying DNA coding sequence, whereby a protein with like properties is obtained. It is thus contemplated that various changes can be made in the peptide sequences of the disclosed compositions, or corresponding DNA sequences that encode said peptides without appreciable loss of their biological utility or activity.

In many instances, a polypeptide variant will contain one or more conservative substitutions. A “conservative substitution” is one in which an amino acid is substituted for another amino acid that has similar properties, such that one skilled in the art of peptide chemistry would expect the secondary structure and hydropathic nature of the polypeptide to be substantially unchanged.

Amino acid substitutions generally are based on the relative similarity of the amino acid side-chain substituents, for example, their hydrophobicity, hydrophilicity, charge, size, and the like. Exemplary substitutions that take various of the foregoing characteristics into consideration are well known to those of skill in the art and include: arginine and lysine; glutamate and aspartate; serine and threonine; glutamine and asparagine; and valine, leucine and isoleucine.

“Homology” or “sequence identity” refers to the percentage of residues in the polynucleotide or polypeptide sequence variant that are identical to the non-variant sequence after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent homology. In particular embodiments, polynucleotide and polypeptide variants have at least about 70%, at least about 75%, at least about 80%, at least about 90%, at least about 95%, at least about 98%, or at least about 99% polynucleotide or polypeptide homology with a polynucleotide or polypeptide described herein.

Such variant polypeptide sequences will share 70% or more (i.e. 80%, 85%, 90%, 95%, 97%, 98%, 99% or more) sequence identity with the sequences recited in the application. In additional embodiments, the described invention provides polypeptide fragments comprising various lengths of contiguous stretches of amino acid sequences disclosed herein. For example, peptide sequences are provided by this invention that comprise at least about 5, 10, 15, 20, 30, 40, 50, 75, 100, 150, or more contiguous peptides of one or more of the sequences disclosed herein as well as all intermediate lengths there between.

The invention also includes nucleic acid sequences encoding part or all of the light and heavy chains of the described inventive antibodies, and fragments thereof. Due to redundancy of the genetic code, variants of these sequences will exist that encode the same amino acid sequences.

The present invention also includes isolated nucleic acid sequences encoding the polypeptides for the heavy and light chains of the HIV antibodies listed in Tables A, B and FIG. 10 A-C; the consensus sequences for the heavy and light chains of SEQ ID NOs: 1 and 2; and insertion sequences SEQ ID NOs: 3 and 4.

In other related embodiments, the described invention provides polynucleotide variants that encode the peptide sequences of the heavy and light chains of the HIV antibodies listed in Tables A, B and FIGS. 10 A-C; the consensus sequences for the heavy and light chains of SEQ ID NOs: 1 and 2; and insertion sequences SEQ ID NOs: 3 and 4. These polynucleotide variants have at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99%, or greater, sequence identity compared to a polynucleotide sequence of this invention, as determined using the methods described herein, (for example, BLAST analysis using standard parameters). One skilled in this art will recognize that these values can be appropriately adjusted to determine corresponding identity of proteins encoded by two nucleotide sequences by taking into account codon degeneracy, amino acid similarity, reading frame positioning, and the like.

The terms “nucleic acid” and “polynucleotide” are used interchangeably herein to refer to single-stranded or double-stranded RNA, DNA, or mixed polymers. Polynucleotides can include genomic sequences, extra-genomic and plasmid sequences, and smaller engineered gene segments that express, or can be adapted to express polypeptides.

An “isolated nucleic acid” is a nucleic acid that is substantially separated from other genome DNA sequences as well as proteins or complexes such as ribosomes and polymerases, which naturally accompany a native sequence. The term encompasses a nucleic acid sequence that has been removed from its naturally occurring environment, and includes recombinant or cloned DNA isolates and chemically synthesized analogues or analogues biologically synthesized by heterologous systems. A substantially pure nucleic acid includes isolated forms of the nucleic acid. Accordingly, this refers to the nucleic acid as originally isolated and does not exclude genes or sequences later added to the isolated nucleic acid by the hand of man.

A polynucleotide “variant,” as the term is used herein, is a polynucleotide that typically differs from a polynucleotide specifically disclosed herein in one or more substitutions, deletions, additions and/or insertions. Such variants can be naturally occurring or can be synthetically generated, for example, by modifying one or more of the polynucleotide sequences of the invention and evaluating one or more biological activities of the encoded polypeptide as described herein and/or using any of a number of techniques well known in the art.

Modifications can be made in the structure of the polynucleotides of the described invention and still obtain a functional molecule that encodes a variant or derivative polypeptide with desirable characteristics. When it is desired to alter the amino acid sequence of a polypeptide to create an equivalent, or even an improved, variant or portion of a polypeptide of the invention, one skilled in the art typically will change one or more of the codons of the encoding DNA sequence.

Typically, polynucleotide variants contain one or more substitutions, additions, deletions and/or insertions, such that the immunogenic binding properties of the polypeptide encoded by the variant polynucleotide is not substantially diminished relative to a polypeptide encoded by a polynucleotide sequence specifically set forth herein.

In additional embodiments, the described invention provides polynucleotide fragments comprising various lengths of contiguous stretches of sequence identical to or complementary to one or more of the sequences disclosed herein. For example, polynucleotides are provided by this invention that comprise at least about 10, 15, 20, 30, 40, 50, 75, 100, 150, 200, 300, 400, 500 or 1000 or more contiguous nucleotides of one or more of the sequences disclosed herein as well as all intermediate lengths there between and encompass any length between the quoted values, such as 16, 17, 18, 19, etc.; 21, 22, 23, etc.; 30, 31, 32, etc.; 50, 51, 52, 53, etc.; 100, 101, 102, 103, etc.; 150, 151, 152, 153, etc.; and including all integers through 200-500; 500-1,000.

In another embodiment of the invention, polynucleotide compositions are provided that are capable of hybridizing under moderate to high stringency conditions to a polynucleotide sequence provided herein, or a fragment thereof, or a complementary sequence thereof. Hybridization techniques are well known in the art of molecular biology. For purposes of illustration, suitable moderate stringent conditions for testing the hybridization of a polynucleotide of this invention with other polynucleotides include prewashing in a solution of 5×SSC, 0.5% SDS, 1.0 mM EDTA (pH 8.0); hybridizing at 50-60° C., 5×SSC, overnight; followed by washing twice at 65° C. for 20 minutes with each of 2×, 0.5×. and 0.2×SSC containing 0.1% SDS. One skilled in the art will understand that the stringency of hybridization can be readily manipulated, such as by altering the salt content of the hybridization solution and/or the temperature at which the hybridization is performed. For example, in another embodiment, suitable highly stringent hybridization conditions include those described above, with the exception that the temperature of hybridization is increased, for example, to 60-65° C. or 65-70° C.

In some embodiments, the polypeptide encoded by the polynucleotide variant or fragment has the same binding specificity (i.e., specifically or preferentially binds to the same epitope or HIV strain) as the polypeptide encoded by the native polynucleotide. In some embodiments, the described polynucleotides, polynucleotide variants, fragments and hybridizing sequences, encode polypeptides that have a level of binding activity of at least about 50%, at least about 70%, and at least about 90% of that for a polypeptide sequence specifically set forth herein.

The polynucleotides of the described invention, or fragments thereof, regardless of the length of the coding sequence itself, can be combined with other DNA sequences, such as promoters, polyadenylation signals, additional restriction enzyme sites, multiple cloning sites, other coding segments, and the like, such that their overall length can vary considerably. A nucleic acid fragment of almost any length is employed. For example, illustrative polynucleotide segments with total lengths of about 10000, about 5000, about 3000, about 2000, about 1000, about 500, about 200, about 100, about 50 base pairs in length, and the like, (including all intermediate lengths) are included in many implementations of this invention.

In some embodiments, the polynucleotide sequences provided herein are used as probes or primers for nucleic acid hybridization, for example, as PCR primers. The ability of such nucleic acid probes to specifically hybridize to a sequence of interest enables them to detect the presence of complementary sequences in a given sample. However, other uses also are encompassed by the described invention, such as the use of the sequence information for the preparation of mutant species primers, or primers for use in preparing other genetic constructions. As such, nucleic acid segments of the described invention that include a sequence region of at least about a 15 nucleotide long contiguous sequence that has the same sequence as, or is complementary to, a 15 nucleotide long contiguous sequence disclosed herein is particularly useful. Longer contiguous identical or complementary sequences, for example, those of about 20, 30, 40, 50, 100, 200, 500, 1000 (including all intermediate lengths) including full length sequences, and all lengths in between, also are used in some embodiments.

Polynucleotide molecules having sequence regions consisting of contiguous nucleotide stretches of 10-14, 15-20, 30, 50, or even of 100-200 nucleotides or so (including intermediate lengths as well), identical or complementary to a polynucleotide sequence disclosed herein, are particularly contemplated as hybridization probes for use in, for example, Southern and Northern blotting, and/or primers for use in, for example, PCR. The total size of fragment, as well as the size of the complementary stretch(es), ultimately depends on the intended use or application of the particular nucleic acid segment. Smaller fragments generally are used in hybridization embodiments, wherein the length of the contiguous complementary region can be varied, such as between about 15 and about 100 nucleotides, but larger contiguous complementarity stretches can be used, according to the length complementary sequences one wishes to detect.

The use of a hybridization probe of about 15-25 nucleotides in length allows the formation of a duplex molecule that is both stable and selective. Molecules having contiguous complementary sequences over stretches greater than 12 bases in length can be utilized, though, in order to increase stability and selectivity of the hybrid, and thereby improve the quality and degree of specific hybrid molecules obtained. Nucleic acid molecules having gene-complementary stretches of 15 to 25 contiguous nucleotides, or even longer where desired, can be utilized.

Hybridization probes are selected from any portion of any of the sequences disclosed herein. All that is required is to review the sequences set forth herein, or to any continuous portion of the sequences, from about 15-25 nucleotides in length up to and including the full length sequence, that one wishes to utilize as a probe or primer. The choice of probe and primer sequences is governed by various factors. For example, one may wish to employ primers from towards the termini of the total sequence.

Further included within the scope of the invention are vectors such as expression vectors, comprising a nucleic acid sequence according to the invention. Cells transformed with such vectors also are included within the scope of the invention.

The present invention also provides vectors and host cells comprising a nucleic acid of the invention, as well as recombinant techniques for the production of a polypeptide of the invention. Vectors of the invention include those capable of replication in any type of cell or organism, including, for example, plasmids, phage, cosmids, and mini chromosomes. In some embodiments, vectors comprising a polynucleotide of the described invention are vectors suitable for propagation or replication of the polynucleotide, or vectors suitable for expressing a polypeptide of the described invention. Such vectors are known in the art and commercially available.

“Vector” includes shuttle and expression vectors. Typically, the plasmid construct also will include an origin of replication (for example, the ColE1 origin of replication) and a selectable marker (for example, ampicillin or tetracycline resistance), for replication and selection, respectively, of the plasmids in bacteria. An “expression vector” refers to a vector that contains the necessary control sequences or regulatory elements for expression of the antibodies including antibody fragment of the invention, in bacterial or eukaryotic cells.

As used herein, the term “cell” can be any cell, including, but not limited to, that of a eukaryotic, multicellular species (for example, as opposed to a unicellular yeast cell), such as, but not limited to, a mammalian cell or a human cell. A cell can be present as a single entity, or can be part of a larger collection of cells. Such a “larger collection of cells” can comprise, for example, a cell culture (either mixed or pure), a tissue (for example, endothelial, epithelial, mucosa or other tissue), an organ (for example, lung, liver, muscle and other organs), an organ system (for example, circulatory system, respiratory system, gastrointestinal system, urinary system, nervous system, integumentary system or other organ system), or an organism (e.g., a bird, mammal, or the like).

Polynucleotides of the invention may synthesized, whole or in parts that then are combined, and inserted into a vector using routine molecular and cell biology techniques, including, for example, subcloning the polynucleotide into a linearized vector using appropriate restriction sites and restriction enzymes. Polynucleotides of the described invention are amplified by polymerase chain reaction using oligonucleotide primers complementary to each strand of the polynucleotide. These primers also include restriction enzyme cleavage sites to facilitate subcloning into a vector. The replicable vector components generally include, but are not limited to, one or more of the following: a signal sequence, an origin of replication, and one or more marker or selectable genes.

In order to express a polypeptide of the invention, the nucleotide sequences encoding the polypeptide, or functional equivalents, may be inserted into an appropriate expression vector, i.e., a vector that contains the necessary elements for the transcription and translation of the inserted coding sequence. Methods well known to those skilled in the art may be used to construct expression vectors containing sequences encoding a polypeptide of interest and appropriate transcriptional and translational control elements. These methods include in vitro recombinant DNA techniques, synthetic techniques, and in vivo genetic recombination. Such techniques are described, for example, in Sambrook, J., et al. (1989) Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Press, Plainview, N.Y., and Ausubel, F. M. et al. (1989) Current Protocols in Molecular Biology, John Wiley & Sons, New York. N.Y.

The present invention also provides kits useful in performing diagnostic and prognostic assays using the antibodies, polypeptides and nucleic acids of the present invention. Kits of the present invention include a suitable container comprising an HIV antibody, a polypeptide or a nucleic acid of the invention in either labeled or unlabeled form. In addition, when the antibody, polypeptide or nucleic acid is supplied in a labeled form suitable for an indirect binding assay, the kit further includes reagents for performing the appropriate indirect assay. For example, the kit may include one or more suitable containers including enzyme substrates or derivatizing agents, depending on the nature of the label. Control samples and/or instructions may also be included. The present invention also provide kits for detecting the presence of the HIV antibodies or the nucleotide sequence of the HIV antibody of the present invention in a biological sample by PCR or mass spectrometry.

“Label” as used herein refers to a detectable compound or composition that is conjugated directly or indirectly to the antibody so as to generate a “labeled” antibody. A label can also be conjugated to a polypeptide and/or a nucleic acid sequence disclosed herein. The label can be detectable by itself (for example, radioisotope labels or fluorescent labels) or, in the case of an enzymatic label, can catalyze chemical alteration of a substrate compound or composition that is detectable. Antibodies and polypeptides of the described invention also can be modified to include an epitope tag or label, for example, for use in purification or diagnostic applications. Suitable detection means include the use of labels such as, but not limited to, radionucleotides, enzymes, coenzymes, fluorescers, chemiluminescers, chromogens, enzyme substrates or co-factors, enzyme inhibitors, prosthetic group complexes, free radicals, particles, dyes, and the like.

According to another embodiment, the present invention provides diagnostic methods. Diagnostic methods generally involve contacting a biological sample obtained from a patient, such as, for example, blood, serum, saliva, urine, sputum, a cell swab sample, or a tissue biopsy, with an HIV antibody and determining whether the antibody preferentially binds to the sample as compared to a control sample or predetermined cut-off value, thereby indicating the presence of the HIV virus.

According to another embodiment, the present invention provides methods to detect the presence of the HIV antibodies of the present invention in a biological sample from a patient. Detection methods generally involve obtaining a biological sample from a patient, such as, for example, blood, serum, saliva, urine, sputum, a cell swab sample, or a tissue biopsy and isolating HIV antibodies or fragments thereof, or the nucleic acids that encode an HIV antibody, and assaying for the presence of an HIV antibody in the biological sample. Also, the present invention provides methods to detect the nucleotide sequence of an HIV antibody in a cell. The nucleotide sequence of an HIV antibody may also be detected using the primers disclosed herein. The presence of the HIV antibody in a biological sample from a patient may be determined utilizing known recombinant techniques and/or the use of a mass spectrometer.

In another embodiment, the present invention provides a method for detecting an HIV antibody comprising a heavy chain comprising a highly conserved consensus sequence and a light chain comprising a highly conserved consensus sequence in a biological sample, comprising obtaining an immunoglobulin-containing biological sample from a mammalian subject, isolating an HIV antibody from said sample, and identifying the highly conserved consensus sequences of the heavy chain and the light chain. The biological sample may be blood, serum, saliva, urine, sputum, a cell swab sample, or a tissue biopsy. The amino acid sequences may be determined by methods known in the art including, for example, PCR and mass spectrometry.

The term “assessing” includes any form of measurement, and includes determining if an element is present or not. The terms “determining”, “measuring”, “evaluating”, “assessing” and “assaying” are used interchangeably and include quantitative and qualitative determinations. Assessing may be relative or absolute. “Assessing the presence of” includes determining the amount of something present, and/or determining whether it is present or absent. As used herein, the terms “determining,” “measuring,” and “assessing,” and “assaying” are used interchangeably and include both quantitative and qualitative determinations.

II. Method of Reducing Viral Replication

Methods for reducing an increase in HIV virus titer, virus replication, virus proliferation or an amount of an HIV viral protein in a subject are further provided. According to another aspect, a method includes administering to the subject an amount of an HIV antibody effective to reduce an increase in HIV titer, virus replication or an amount of an HIV protein of one or more HIV strains or isolates in the subject.

According to another embodiment, the present invention provides a method of reducing viral replication or spread of HIV infection to additional host cells or tissues comprising contacting a mammalian cell with the antibody, or a portion thereof, which binds to an antigenic epitope on gp120.

III. Method of Treatment

According to another embodiment, the present invention provides a method for treating a mammal infected with a virus infection, such as, for example, HIV, comprising administering to said mammal a pharmaceutical composition comprising the HIV antibodies disclosed herein. According to one embodiment, the method for treating a mammal infected with HIV comprises administering to said mammal a pharmaceutical composition that comprises an antibody of the present invention, or a fragment thereof. The compositions of the invention can include more than one antibody having the characteristics disclosed (for example, a plurality or pool of antibodies). It also can include other HIV neutralizing antibodies as are known in the art, for example, but not limited to, VRC01, PG9 and b12.

Passive immunization has proven to be an effective and safe strategy for the prevention and treatment of viral diseases. (See, for example, Keller et al., Clin. Microbiol. Rev. 13:602-14 (2000); Casadevall, Nat. Biotechnol. 20:114 (2002); Shibata et al., Nat. Med. 5:204-10 (1999); and Igarashi et al., Nat. Med. 5:211-16 (1999), each of which are incorporated herein by reference). Passive immunization using human monoclonal antibodies provides an immediate treatment strategy for emergency prophylaxis and treatment of HIV.

Subjects at risk for HIV-related diseases or disorders include patients who have come into contact with an infected person or who have been exposed to HIV in some other way. Administration of a prophylactic agent can occur prior to the manifestation of symptoms characteristic of HIV-related disease or disorder, such that a disease or disorder is prevented or, alternatively, delayed in its progression.

For in vivo treatment of human and non-human patients, the patient is administered or provided a pharmaceutical formulation including an HIV antibody of the invention. When used for in vivo therapy, the antibodies of the invention are administered to the patient in therapeutically effective amounts (i.e., amounts that eliminate or reduce the patient's viral burden). The antibodies are administered to a human patient, in accord with known methods, such as intravenous administration, for example, as a bolus or by continuous infusion over a period of time, by intramuscular, intraperitoneal, intracerobrospinal, subcutaneous, intra-articular, intrasynovial, intrathecal, oral, topical, or inhalation routes. The antibodies can be administered parenterally, when possible, at the target cell site, or intravenously. In some embodiments, antibody is administered by intravenous or subcutaneous administration. Therapeutic compositions of the invention may be administered to a patient or subject systemically, parenterally, or locally. The above parameters for assessing successful treatment and improvement in the disease are readily measurable by routine procedures familiar to a physician.

For parenteral administration, the antibodies may formulated in a unit dosage injectable form (solution, suspension, emulsion) in association with a pharmaceutically acceptable, parenteral vehicle. Examples of such vehicles include, but are not limited, water, saline, Ringer's solution, dextrose solution, and 5% human serum albumin. Nonaqueous vehicles include, but are not limited to, fixed oils and ethyl oleate. Liposomes can be used as carriers. The vehicle may contain minor amounts of additives such as substances that enhance isotonicity and chemical stability, such as, for example, buffers and preservatives. The antibodies can be formulated in such vehicles at concentrations of about 1 mg/ml to 10 mg/ml.

The dose and dosage regimen depends upon a variety of factors readily determined by a physician, such as the nature of the infection, for example, its therapeutic index, the patient, and the patient's history. Generally, a therapeutically effective amount of an antibody is administered to a patient. In some embodiments, the amount of antibody administered is in the range of about 0.1 mg/kg to about 50 mg/kg of patient body weight. Depending on the type and severity of the infection, about 0.1 mg/kg to about 50 mg/kg body weight (for example, about 0.1-15 mg/kg/dose) of antibody is an initial candidate dosage for administration to the patient, whether, for example, by one or more separate administrations, or by continuous infusion. The progress of this therapy is readily monitored by conventional methods and assays and based on criteria known to the physician or other persons of skill in the art. The above parameters for assessing successful treatment and improvement in the disease are readily measurable by routine procedures familiar to a physician.

Other therapeutic regimens may be combined with the administration of the HIV antibody of the present invention. The combined administration includes co-administration, using separate formulations or a single pharmaceutical formulation, and consecutive administration in either order, wherein preferably there is a time period while both (or all) active agents simultaneously exert their biological activities. Such combined therapy can result in a synergistic therapeutic effect. The above parameters for assessing successful treatment and improvement in the disease are readily measurable by routine procedures familiar to a physician.

The terms “treating” or “treatment” or “alleviation” are used interchangeably and refer to both therapeutic treatment and prophylactic or preventative measures; wherein the object is to prevent or slow down (lessen) the targeted pathologic condition or disorder. Those in need of treatment include those already with the disorder as well as those prone to have the disorder or those in whom the disorder is to be prevented. A subject or mammal is successfully “treated” for an infection if, after receiving a therapeutic amount of an antibody according to the methods of the present invention, the patient shows observable and/or measurable reduction in or absence of one or more of the following: reduction in the number of infected cells or absence of the infected cells; reduction in the percent of total cells that are infected; and/or relief to some extent, one or more of the symptoms associated with the specific infection; reduced morbidity and mortality, and improvement in quality of life issues. The above parameters for assessing successful treatment and improvement in the disease are readily measurable by routine procedures familiar to a physician.

The term “therapeutically effective amount” refers to an amount of an antibody or a drug effective to treat a disease or disorder in a subject or mammal.

Administration “in combination with” one or more further therapeutic agents includes simultaneous (concurrent) and consecutive administration in any order.

“Carriers” as used herein include pharmaceutically acceptable carriers, excipients, or stabilizers that are nontoxic to the cell or mammal being exposed thereto at the dosages and concentrations employed. Often the physiologically acceptable carrier is an aqueous pH buffered solution. Examples of physiologically acceptable carriers include, but not limited to, buffers such as phosphate, citrate, and other organic acids; antioxidants including, but not limited to, ascorbic acid; low molecular weight (less than about 10 residues) polypeptide; proteins, such as, but not limited to, serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as, but not limited to, polyvinylpyrrolidone; amino acids such as, but not limited to, glycine, glutamine, asparagine, arginine or lysine; monosaccharides, disaccharides, and other carbohydrates including, but not limited to, glucose, mannose, or dextrins; chelating agents such as, but not limited to, EDTA; sugar alcohols such as, but not limited to, mannitol or sorbitol; salt-forming counterions such as, but not limited to, sodium; and/or nonionic surfactants such as, but not limited to, polyoxyethylenesorbitan monolaurate (e.g. TWEEN); polyethylene glycol (PEG), and poloxamers (e.g. PLURONICS).

Where a value of ranges is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges which may independently be included in the smaller ranges is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either both of those included limits are also included in the invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, the preferred methods and materials are now described. All publications mentioned herein are incorporated herein by reference in their entireties.

Example 1 Materials, Methods and Instrumentation

Samples.

Human samples were collected after signed informed consent in accordance with Institutional Review Board (IRB)-reviewed protocols by all participating institutions. Patient 1 was selected from a cohort of long-term non-progressors followed at the Aaron Diamod Aids Research Center, New York. Patients 3 and 8 were selected from a group of elite controllers that were followed at the Ragon Institute in Boston. Patients 1, 3 and 8 were selected based on their broad neutralizing serum activity against a standard panel of HIV isolates. Patient 12 was selected from the Protocol G Cohort of the “International Aids Vaccine Initiative” based on broad serum neutralizing activity.

Staining, Single-Cell Sorting and Antibody Cloning.

Staining and single cell sorting of 2CC-Core and gp140 specific Ig+ memory B cells was performed (J. F. Scheid et al., Nature 458, 636 (Apr. 2, 2009)). Briefly, CD19+ B cells were enriched from peripheral blood mononuclear cells using anti human CD19 magnetic MACS beads (Miltenyi Biotec) and subsequently stained with anti human CD20 and anti human IgG antibodies (Becton Dickinson) as well as biotinylated 2CC-Core (B. Dey et al., PLoS Pathog 5, e1000445 (May, 2009)) or YU2-gp140 trimer (R. Diskin, P. M. Marcovecchio, P. J. Bjorkman, Nat Struct Mol Biol 17, 608 (May, 2010)) followed by detection with streptavidin coupled phycoerythrin (PE, Beckton Dickinson). Single cells were sorted on a FACSAria III cell sorter (Becton Dickinson), excluding cell doublets, into 96-well PCR plates (Denville) containing 4 l/well of ice-cold 0.5×phosphate-buffered saline (PBS) containing 10 mM DTT, 8 U RNAsin® (Promega), 0.4 U 5′-3′ Prime RNAse Inhibitor™ (Eppendorf). Plates were sealed with Microseal® ‘F’ Film (BioRad), immediately frozen on dry ice before storage at −80° C.

cDNA synthesis and Ig amplification were performed (H. Wardemann et al., Science 301, 1374 (Sep. 5, 2003)) with following modifications:

Instead of using the original primer sets, first and second immunoglobulin specific PCRs were carried out using the primers described in Table 1 in a semi-nested approach. Cloning of heavy and light chain PCR products into their respective expression vectors was performed and 100% identity of cloned expression plasmids with the original PCR product confirmed by sequencing before expression of the antibodies in HEK 293 cells.

ELISAs.

High-binding 96-well ELISA plates (Costar) were coated overnight with 100 ng/well of purified antigens (gp140, gp120, gp41, gp120^(core) and 2CC-core) (B. Dey et al., PLoS Pathog 5, e1000445 (May, 2009)) and mutant proteins (gp120 D368R, gp120 I420R) in PBS. After washing, plates were blocked 2 h with 2% BSA, 1 μM EDTA, 0.05% Tween-PBS (Blocking buffer) and then, incubated 2 h with IgG antibodies diluted at 4 μg/ml and several consecutive 1:4 dilutions in PBS. After washing, the plates were developed by incubation for 1 h with goat HRP-conjugated anti-mouse IgG (Jackson ImmunoReseach) (at 0.8 μg/ml in blocking buffer) and by adding 100 μl of HRP chromogenic substrate (ABTS solution, Invitrogen). Optical densities were measured at 405 nm (OD_(405 nm)) using an ELISA microplate reader (Molecular Devices). Background values given by incubation of PBS alone in coated wells were subtracted. IgG Antibodies were tested for polyreactivity (H. Mouquet et al., Nature 467, 591 (Sep. 30, 2010)) and considered polyreactive when they recognized at least two structurally different antigens out of the four tested; ssDNA, dsDNA, insulin, and LPS. Threshold values for reactivity were determined by using control antibodies mGO53 (negative), eiJB40 (low positive), and ED38 (high positive).

Neutralization Assays:

Neutralization screens were performed (D. C. Montefiori, Curr Protoc Immunol Chapter 12, Unit 12 11 (January, 2005)). In brief, neutralization was detected as reduction in luciferase reporter gene expression after single round infection in Tzm-bl cells. In order to rule out unspecific antiviral activity in antibody samples MuLV (murine leukemia virus) was used as a negative control.

Clone Specific Identification of Bone Marrow Plasma Cells.

Bone marrow plasma cells were stained with anti human CD138 and anti CD19 antibodies (Becton Dickinson) after Ficoll purification of mononuclear cells from bone marrow aspirates using Ficoll-Paque (GE Healthcare). CD138+CD19+ human plasma cells were bulk sorted on a FACSAriaIII cell sorter (Becton Dickinson) and RNA isolation performed on 100.000 cells using Trizol LS reagent (Invitrogen) according to the manufacturers instructions. RNA was reverse transcribed using Superscript III reverse transcriptase (Invitrogen) according to manufacturers instructions. cDNA was then subjected to Immunoglobulin specific PCR with following modifications: 1 μl of cDNA was amplified in 2 rounds of nested immunoglobulin heavy chain clone specific PCR using first round forward leader and constant region reverse primers shown in Table 1 followed by clone specific forward and reverse primers designed based on sequencing results from single cell analysis. PCR products were gel purified and cloned into TOPO TA vectors (Invitrogen) according to the manufacturers instructions. Colonies were screened by PCR with clone specific primers and sequenced.

Surface Plasmon Resonance.

All experiments were performed with a Biacore T100 (Biacore, Inc) in HBS-EP+ running buffer (Biacore, Inc) at 25° C. as described previously (Mouquet2010). YU-2 gp140 and 2CC-core proteins at 12.5 μg/mL were immobilized on CM5 chips (Biacore, Inc.) by amine coupling at pH 4.5 resulting in an immobilization level of 100 RUs. For kinetic measurements on the gp140- and 2CC-core-derivatized chips, IgGs were injected through flow cells at 700 nM and 4 successive 1:2-dilutions in HBS-EP+ running buffer (Biacore, Inc.) at flow rates of 40 μL/min with 3 min association and 5 min dissociation. The sensor surface was regenerated between each experiment with a 30 second injection of 10 mM glycine-HCl pH 2.5 at a flow rate of 50 μL/min. Off rate (k_(d) (s⁻¹)), on rate (k_(a) (M⁻¹ s⁻¹) and binding constants (K_(D)(M) or K_(A) (M⁻¹) were calculated after subtraction of backgrounds (binding to control flow cells and signal of the HBS-EP+ running buffer) using Biacore T100 Evaluation software using the kinetic analysis and the 1:1 binding model. The sensorgrams showed in FIG. 2 and FIG. 8 are derived from the Biacore data processing using Scrubber 2 software (Center for Biomolecular Interaction Analysis, University of Utah).

CD4i Site Induction.

293T cells were transfected with gp160^(BAL.26)Δc or gp160^(YU.2)Δc in a pMX-IRES-GFP construct (Pietzsch et al. 2010) using Fugene™6 (Roche) at a 1:2 plasmid:Fugene ratio. After 48 hours 293T cells were washed with PBS and detached with Trypsin-free cell dissociation buffer (Gibco) and resuspended at a concentration of 10⁷ cells/ml in FACS buffer (1×PBS, 2% FBS, 2 mM EDTA). sCD4 (Progenics Pharmaceuticals, Inc.) and mAbs were added to gp160-expressing 293T cells in a 1:4 dilution series starting with a final concentration of 40 μg/ml. mGO is a negative control antibody that does not bind to gp160Δc (H. Mouquet et al., Nature 467, 591 (Sep. 30, 2010)). After incubation for 15 min on ice cells were split and stained for 25 min on ice with an Alexa647-labeled CD4-induced site mAb (3-67; (J. F. Scheid et al., Nature 458, 636 (Apr. 2, 2009)) or an Alexa647-labeled control mAb (i.e. PG16; L. M. Walker et al., Science 326, 285 (Oct. 9, 2009)) or 2G12 for gp160^(YU.2) and 2G12 for gp160^(BAL.26)). Antibody labeling was performed by using Alexa Fluor® 647 Microscale Protein Labeling Kit (Invitrogen). Cells were analyzed on an LSRFortessa cell analyzer (BD Bioscience).

Crystallization.

The 3BNC60 IgG was expressed by transient expression in HEK293-6E cells and prepared the Fab fragment was prepared by papain cleavage (R. Diskin, P. M. Marcovecchio, P. J. Bjorkman, Nat Struct Mol Biol 17, 608 (May, 2010). Crystallization screens were conducted at 20° C. by vapor diffusion in nL sitting drops using a Mosquito™ (TTP LabTech) crystallization robot on MRC crystallization plates (Jena Bioscience). We combined 3BNC60 Fab at a concentration of 9.5 mg/ml with reservoir solution in a 1:1 ratio to create 400 nL drops. Initial crystallization hits were obtained using the PEGRx HT™ (Hampton Research) crystallization screen and further optimized manually. Crystals suitable for data collection grew after several weeks in 11.7% polyethylene glycol 20,000, 0.1 M sodium acetate pH 5.0, 100 mM potassium/sodium tartrate, 20 mM lithium sulfate, 10 mM N-Cyclohexyl-2-aminoethanesulfonic acid (CHES) pH 9.5 in the monoclinic space group P2₁ with two Fabs in the asymmetric unit. Crystals were soaked in reservoir solution supplemented with 15% glycerol for 2 hours before immersing in reservoir solution supplemented with 30% glycerol and flash cooling in liquid nitrogen. Diffraction data were collected at the Stanford Synchrotron Radiation Lightsource (SSRL) beam-line 12-2 at 100 K using a Pilatus 6M detector. Data were indexed, integrated, and scaled using XDS W. Kabsch, Acta Crystallogr D Biol Crystallogr 66, 125 (February, 2010) (Table 8). Molecular replacement was conducted using Phaser with the V_(H) and C_(H)1 domains from the anti-tumor antibody CTM01 (PDB code 1AD9) and with the V_(L) and C_(L) domains of the anti-gp120 b13 antibody (PDB code 3IDX) as search models. Model building and refinement to 2.65 Å resolution was done iteratively using Phenix P. Emsley, B. Lohkamp, W. G. Scott, K. Cowtan, Acta Crystallogr D Biol Crystallogr 66, 486 (April, 2010) and Coot (P. Emsley, B. Lohkamp, W. G. Scott, K. Cowtan, Acta Crystallogr D Biol Crystallogr 66, 486 (April, 2010)). The structure was refined using a maximum-likelihood target function and non-crystallographic symmetry restraints. The final model (R_(work)=20.7%; R_(free)=25.7%) includes 6478 protein atoms, 146 water molecules and 28 sugar atoms (Table 8). 91.9%, 7.6% and 0.5% of the residues were in the favored, allowed, and disallowed regions, respectively, of the Ramachandran plot. Structural analyses and visualization were done using PyMol (The PyMOL Molecular Graphics System, Version 1.3, Schrödinger, LLC). The 3BNC60 structure consists of residues 3-205 for the light chain (including the first N-acetylglucosamine within an N-linked carbohydrate attached to Asn72) and 2-217 for the heavy-chain. Residues at the termini residues and residues 133-140 within the C_(H)1 domain are disordered.

Mass Spectrometry.

IgG was purified from serum using ProteinG Sepharose (GE Healthcare) according to the manufacturers instructions. IgGs were then digested with immobilized papain (Pierce) and digested Fab-Fc fragment mixes incubated with saturating quantities of biotinylated 2CC-Core protein. Streptavidin coupled Dynabeads (Invitrogen) were added after incubation for 15 minutes at room temperature and subjected to 10 rounds of washing with Phosphate Buffered Saline (Gibco). Bound Fab fragments were eluted with lithium dodecyl sulfate buffer (Invitrogen) at 95 C and sample purity confirmed with SDS-polyacrylamide gel electrophoresis followed by silver stain or coomassie staining before analysis by mass spectrometry.

Isolated Fab fragments were reduced with dithiothreitol, alkylated using iodoacetamide, resolved by 1D gel electrophoresis on a 4-12% NuPAGE Novex Bis-Tris gel (Invitrogen), and stained with Coomassie Blue (Thermo Fisher). The Fab fragments were excised from the gel, and digested using 200 ng of trypsin (Promega). The resulting peptides were isolated using reverse phase resin (PORS 20 R2, Applied Biosystem) and eluted using an aliquot of 40% acetonitrile in 0.5% acetic acid and a second aliquot of 80% acetonitrile in 0.5% acetic acid. Acetonitrile was removed using a speedvac (Thermo Fisher Scientific) and aliquots of the remaining solution pressure loaded onto self-packed PicoFrit® column (New Objective, Woburn, Mass.) with integrated emitter tip (360 m O.D., 50 μm I.D., 10 m tip), packed with 6 cm of reverse-phase C18 material (ReproSil-Pur C18-AQ, 3 m beads from Dr. Maisch GmbH) and interfaced to a Agilent 1200 series HPLC system (Agilent) with either a LTQ Orbitrap™ XL mass spectrometer or a LTQ Orbitrap Velos™ mass spectrometer (Thermo Fisher Scientific) using a home-built micro electrospray source. The peptides were eluted into the mass spectrometer with the following gradient: 0 to 5% B in 5 min, 40% B in 125 min, 60% B in 150 min, 100% B in 165 min (A=0.1 M acetic acid, B=70% acetonitrile in 0.1 M acetic acid, flow rate 90 nL/min). Both instruments were operated in the data dependent mode and for both mass spectrometers the target value was set to 5e5 ions and a resolution of 60,000 (at 400 m/z). For analysis on the LTQ Orbitrap™ XL a full scan was followed by 8 MS/MS scans on the 8 most abundant ions from that full scan. The peptides (only charge states >1) were isolated with a 2 Da window, target window of 1e4 ions, dissociated via CAD (normalized collision energy=35, activation Q=0.25, activation time 30 msec) and mass analyzed in the LTQ. For analysis on the LTQ Orbitrap™ Velos a full scan was followed by 10 MS/MS scans at 7,500 resolution on the 10 most abundant ions from the immediate preceding full scan. The peptides (only charge state >2) were isolated with a 3 Da window, target window of 2e5 ions, dissociated via HCD (normalized collision energy=40, activation time 0.100 msec) and mass analyzed in the Orbitrap. For either instrument the ions selected for MS/MS were set on an exclusion list for 30 seconds. The resulting MS/MS spectra were searched against the Human IPI and in-house patient specific IgG database using Xtandem!, peptides were automatically compared to tryptic peptides in the human IPI and our in-house patient specific database. Peptide hits corresponding to patient specific IgG were manually confirmed.

Multiple Sequence Alignments.

All multiple sequence alignments were conducted using CLUSTALW2 with default parameters (weight matrix: GONNET for proteins and UIB for DNA, gap open=10, gap extension 0.1). Alignments shading were generated using TeXshade package.

Alignment Consensus.

The consensus sequences for multiple alignments were generated based on identity and similarity between residues (>=70%). The amino acids were grouping due similarity as: FYW, ILVM, RK, DE, GA, ST and NQ.

Phylogenetic Germline Trees.

The relationship between sequences was generated using the Neighbor-Joining method. The bootstrap consensus tree inferred from 1000 replicates was taken to represent the relationship. Branches corresponding to partitions reproduced in less than 50% bootstrap replicates are collapsed. The percentage of replicate trees in which the associated sequence clustered together in the bootstrap test (1000 replicates) are shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the number of differences method and are in the units of the number of amino acid differences per sequence. All ambiguous positions were removed for each sequence pair. Evolutionary analyses were conducted in MEGA5.

R/S Ratio Calculation.

DNA sequences were superposed over the proteins alignments to replacement/substitution calculation. All gaps positions were removed from the analysis. The R/S ratio analysis was conducted using Perl scripts.

Example 2 Isolating HIV Antibodies

To determine whether HIV antibody cloning is limited because of somatic mutation, a new series of primers was designed to avert this potential problem (Table 1). The new primer set was tested by sorting B cells that bind to an HIV-gp120 core protein lacking the V1-3 loops and containing a pair of stabilizing disulfide bonds (2CC-core). In contrast to the re-surfaced bait used to clone VRC01, the 2CC-core bait also allows capture of antibodies to the CD4-induced co-receptor binding site (CD4i).

In side-by-side comparisons, the new primer set increased recovery of IgH chains when compared to the initial primer set (FIG. 4(a)). The antibodies obtained with the new primer set were more mutated (average 35.6 vs. 19.8 p=<0.0001 and maximum 85 vs. 50 for IgH) and included clones that were not found with the original primer set (FIG. 4(a)). To determine whether the new primers rescue VRC01-like antibodies from cells that had been sorted with YU2 gp140, frozen cDNA samples from that individual which had already been examined exhaustively with the original primer set without producing any VRC01 related clones were examined. In 80 wells, 3 antibodies corresponding to VRC01 variants as determined by the IgH and IgL sequences were found (FIGS. 5A and B). It was concluded that VRC01-like antibodies were captured by the gp140 trimer, and that primers that were specifically designed to clone highly mutated antibodies captured a larger fraction of anti-HIV antibodies from the memory B cells of patients with high titers of broadly neutralizing antibodies.

Four unrelated HIV infected individuals, including 2 Caucasians, 1 Hispanic and 1 African donor, showing high titers of broadly neutralizing antibodies were examined using the 2CC-core bait, including 2 individuals whose previously cloned antibodies could not account for their serologic activity (Table 2 and FIGS. 6A and B). 576 antibodies representing 201 different unique and diversified clones were obtained from a starting population of 1.5×10⁵ IgG⁺ memory B cells (Table 3).

Example 3 Binding Specificity of HIV Antibodies

The size of the antibody clones captured by 2CC-core bait differed widely ranging from 2-76 diversified members (Table 3). To determine whether the antibodies captured by the 2CC-core bind to the HIV spike, ELISAs were performed using YU2 gp120 on representative members of each expanded clone. All of the antibodies tested bound to gp120 (Table 3).

The site of antibody binding on the HIV spike was mapped using mutant proteins that interfere with either the CD4bs (gp120(D368R)), or the CD4-induced co-receptor binding site (CD4i, gp120(I420R)). As reported, X. Wu et al., Science 329, 856 (Aug. 13, 2010), VRC01 is classified as a CD4bs antibody since it is sensitive to the D368R mutation, but because of the proximity of the CD4i site, it also shows some sensitivity to the I420R mutation. NIH45-46, which is a VRC01 variant, and antibodies 3BNC60, 8ANC131, and 12A12 showed ELISA patterns that were similar to VRC01 (These clonal members were selected based on neutralizing activity, Table 3). Other clones, including 1B2530, and 8ANC195, were equally sensitive to both mutations and could not be classified precisely based solely on ELISA.

To determine whether the antibodies are polyreactive, ELISAs were performed on purified ssDNA, dsDNA, insulin, and LPS. 63% of the anti-2CC Core antibodies tested were polyreactive. It was concluded that the majority of the antibodies captured by the 2CC-bait recognize either the CD4bs or the CD4i site on gp120 and many are also polyreactive.

Example 4 Somatic Hypermutation

Somatic hypermutation is required for development of high affinity antigen binding and in some cases contributes to polyreactivity of anti-HIV antibodies. To test if this is the case for highly mutated 2CC-core specific antibodies, 4 representative antibodies were reverted to the corresponding germline. Reversion led to complete loss of antigen binding in ELISA for all 4 clones tested and to loss of polyreactivity.

Example 5 HIV Neutralization

HIV neutralizing activity was measured in standardized in vitro assays using an initial panel of 8 viruses including 3 tier 1 Clade A, B and C, and 5 tier 2 Clade B Env pseudovirus variants (M. S. Seaman et al., J Virol 84, 1439 (February, 2010)). The neutralizing activity of the antibodies was compared to VRC01 and purified serum IgG from the donors (FIG. 1A, Table 4 and FIG. 6). Antibodies showing high levels of neutralizing activity were further tested on a panel of 15 additional tier 2 Clade A, B, C, D, G, AG and AE Env pseudovirus variants (FIG. 1B, Table 5) including 5 viruses that are resistant to VRC01 (FIG. 1B and Table 5).

90% of all of the antibodies tested showed some neutralizing activity and 6 clones contained antibody variants that showed high levels of potency and breadth (FIGS. 1A, B and C and Tables 4 and 5). These clones were also the most abundant among those captured by the 2CC-bait in each of the four patients studied (Table 3). The most impressive of the new antibodies, 3BNC117 belonging to a clone with 76 members, showed an average IC₈₀ on a combined group of 14 tier 2 viruses of 0.5 μg/ml as compared to 1.8 μg/ml for VRC01 (FIG. 1C, Tables 4 and 5).

Only 4 of the 20 viruses tested were more sensitive to VRC01 than 3BNC117, whereas 14 were more sensitive to 3BNC117 including DU172.17 which is completely resistant to VRC01 but sensitive to 3BNC117 (FIGS. 1B and C). NIH45-46, a new variant of VRC01, is more potent than VRC01 on 15 of the 20 viruses tested but still less potent than 3BNC117 (FIGS. 1B and C and Tables 4, and 5).

There was substantial variation in neutralizing breadth and potency among the members of the 5 most potent neutralizing antibody clones. For example, 3BNC156, a variant of 3BNC117, neutralized only 2 of the viruses in the initial panel and at much higher concentrations than 3BNC117 (FIG. 1A and Table 4) and 3BNC55, another variant, was intermediate between the two showing activity against 6 viruses at an average IC₅₀ of 4 μg/ml (FIG. 1 and Table 4). Finally, the most active antibodies were highly hypermutated. The average number of mutations for the top 10 antibodies was 72 for V_(H) and 45 for V_(L), and this was associated with their breadth and potency (Tables 4 and 5). Reversion of the mutated residues to germline resulted in a complete loss of neutralizing activity for all of the antibodies tested.

Example 6 Identification of Diagnostic Peptides

The foregoing cloning strategy captured antibodies produced by antigen binding memory B cells, but circulating antibodies are not produced by these cells, and originate instead from plasma cells in the bone marrow. However, cognate antigen cannot be used as bait to capture plasma cells because they do not express surface Ig A. (Radbruch et al., Nat Rev Immunol 6, 741 (October, 2006)). In addition, the relationship between plasma cells in the bone marrow and circulating memory B cells is not defined precisely. To determine whether the antibodies cloned from memory B cells are also found in the bone marrow plasma cell compartment, CD138-expressing plasma cells were purified from paired bone marrow samples from 2 of the 4 individuals studied and used PCR to specifically amplify IgV_(H) genes for the more potent antibodies cloned from memory B cells in these individuals. The following were the clone specific primers for RU01: CTGCAACCGGTGTACATTCTCAAGTGCAACTGGTGC (FWRD) (SEQ ID NO. 584), CTGCAACCGGTGTACATTCTCAGGTCCATTTGTCACAG (FWRD), (SEQ ID NO. 585) TGCGAAGTCGACGCTGACGAGACAGTGACCTGC (REV) (SEQ ID NO. 586), TGCGAAGTCGACGCTGAAGAGACAATAATTTG (REV) (SEQ ID NO. 587), TGCGAAGTCGACGCTGACGAGACAATAACT (REV) (SEQ ID NO. 588) and for RU10: CTGCAACCGGTGTACATTTTCAGGGGCACTTGGTG (FWRD) (SEQ ID NO. 589), TGCGAAGTCGACGCTGAGGTGACGATGACCGTG (REV) (SEQ ID NO. 590). Members of the selected clones and large numbers of additional variants were readily identified in both patients.

To verify that these antibodies can also be found in serum, IgG purified from the serum of the same 2 and one additional individual were adsorbed on the 2CC-core bait and mass spectrometry was performed on the eluted IgG (FIG. 1D, FIG. 7 and FIGS. 10A-C). Diagnostic peptides were found for the highly active antibody variants in all cases (FIG. 7, FIG. 10A-C). It was concluded that broad and potent anti-HIV antibodies cloned from memory B cells were also found in the bone marrow plasma cell compartment, and in the circulating IgGs of patients with high serum titers of broadly neutralizing antibodies.

Example 7 HIV Antibody Binding Characteristics

To determine whether antibody affinity to gp120 is related to neutralizing activity, the binding of the highly active antibodies, selected clonal relatives and germline reverted progenitors were compared using Surface Plasmon Resonance (SPR) (FIGS. 2A and B, FIG. 8 and Table 6).

The top neutralizing antibodies showed affinities (K_(A)) ranging from ≅10⁷-10¹² (M⁻¹) on YU2 gp140 trimers and ≅10⁷-10¹¹ (M⁻¹) on the 2CC-core (FIGS. 2A and B and Table 6). Consistent with their decreased neutralizing potency and breadth, 3BNC66, 3BNC156 and 3BNC55 displayed lower affinities on YU2 gp140 trimers than 3BNC117, but surprisingly, affinities to 2CC-core did not correlate with neutralizing activity (FIG. 1, FIG. 8, Table 4 and Table 6). Binding by SPR was not detected for any of the germline reverted antibodies tested (FIG. 2B, Table 6). It was concluded that the anti-HIV antibodies captured by the YU2 2CC-core tended to show higher affinity to the corresponding gp140 trimer than to the 2CC-core.

When VRC01 binds to the HIV spike it produces large conformational changes that mimic CD4 binding and expose the CD4i site. By contrast, b12 and most other known anti-CD4bs antibodies do not.

To determine whether this is a shared feature of the highly active antibodies, HIV-BAL.26Δc or -YU2 gp160Δc was expressed on the surface of HEK 293T cells and CD4i antibody binding measured in the presence or absence of CD4 or anti-CD4bs antibodies (FIG. 2C). With one exception, all of the highly active antibodies tested resembled CD4 and VRC01 in that they facilitated anti-CD4i antibody binding to either HIV-BAL.26 or YU2 gp160Δc or both (FIG. 2C).

The only highly active antibody that did not share this characteristic, 8ANC195, was not a traditional anti-CD4bs antibody in that it was equally sensitive to the D368R and I420R mutations (Table 3). In addition, it differed from the other highly active antibodies in its neutralization pattern: it did not neutralize any of the tier 1 viruses and showed potent activity against H086.8, a clade B virus resistant to all other antibodies tested including 3BNC117, VRC01 and b12 (FIGS. 1 A and B and Tables 4 and 5).

Example 8 HIV Antibody Sequence Identity

To determine whether highly active anti-CD4bs antibodies share common sequence features, the 10 best antibodies: 2 variants each from 5 independently derived antibody clones from 5 different patients were aligned (FIG. 3). Comparison of the IgV_(H) regions revealed a highly conserved consensus sequence covering 68 IgV_(H) residues (FIG. 3A). The IgV_(H) consensus included 6 of VRC01-gp120 contact residues, including VRC01-Arg 71, which mimics the key interaction of Arg59_(CD4) and Asp368_(gp120) (FIG. 3A). Moreover, the consensus, including the 6 contact residues, was entirely conserved in both of the closely related germline IgV_(H) genes (V_(H)1-2 and V_(H)1-46) that give rise to all of the antibodies in this class (FIGS. 3A and B).

The codons encoding the consensus residues were highly somatically mutated in the 10 selected antibodies, nevertheless the amino acid sequence was conserved (FIG. 9). The ratio of replacement to silent mutations in the consensus residues ranged from 0.7-1.7, whereas it was 3.5-22 in the non-consensus residues indicating that conservation of the consensus is strongly selected (Table 7). In contrast to the heavy chain, the light chain of VRC01 made only 8 out of a total of 32 contacts with gp120. Consistent with its more limited role, comparison of the light chain sequences of the same antibodies uncovered a less extensive consensus covering 53 IgV_(L) residues including 3 VRC01-gp120 contact residues (FIG. 3B). Finally, like the heavy chains, the light chains arose from a limited set of germline genes: 2 were derived from IgK1D-33, 2 from IgK3-11, and one from IgL1-47 (FIG. 3B and Table 3). Antibody 8ANC195, which differed from the others in several important respects did not entirely conform to the consensus and did not arise from related heavy or light chains (FIGS. 3A and B) It was concluded that there is significant sequence convergence among highly active agonistic anti-CD4bs antibodies (HAADs).

Example 9 Crystal Structure of 3BNC60 Fab

To determine whether the structure of the antibodies in different patients is also conserved, the crystal structure of the 3BNC60 Fab was solved to 2.65 Å resolution and compared it to VRC01. The structure revealed the four domains, V_(H), C_(H)1, V_(L), and C_(L), of a canonical Fab and the complementarity-determining regions (CDRs) within V_(H) and V_(L) that form the antigen binding site. The two Fabs in the 3BNC60 asymmetric unit were almost identical; however, the conformation of residues 74-78 in the loop connecting strands D and E varied slightly due to different chemical environments formed by crystal lattice contacts.

Superimposition of the V_(H) domains from 3BNC60 and VRC01 in the VRC01-gp120 co-crystal structure (T. Zhou et al., Science 329, 811 (Aug. 13, 2010)) yielded a root mean square deviation (rmsd) of 1.3 Å (calculated for 111 Cα atoms) with major differences confined to CDR2 residues 58-65 (3BNC60 numbering). Superimposing the structures indicated conservation of the recognition interface with gp120. For example, Arg72_(3BNC60) adopted a similar conformation as Arg71_(VRC01), which mimics an important salt bridge normally formed between Arg59_(CD4) and Asp368_(gp120). In addition, Trp47_(3BNC60) adopted the same conformation as Trp47_(VRC01), a residue that contacts gp120 and is involved with a complex network of interactions of aromatic and aliphatic residues that stabilize the conformations of CDRH3 and CDRL3. Gln65_(3BNC60), which corresponds to Gln64_(VRC01), is within the residue segment (residues 58-65) that differs in structure from VRC01. The conformation of this region of 3BNC60, which is involved in a lattice contact in the crystals, is likely to change upon binding gp120, as it would clash with the CD4-binding loop on gp120.

Superimposing the 3BNC60 and VRC01 VL domains yielded an rmsd of 0.9 Å (calculated for 95 Cα atoms) and showed that some of gp120-contacting residues are structurally conserved; Tyr91_(3BNC60) and Glu91a_(3BNC60) adopted similar conformations as Tyr91_(VRC01) and Glu96_(VRC01), which engaged loop D of gp120 via polar interactions. Overall, these structural comparisons suggested that 3BNC60 binds gp120 with the same architecture as observed for the binding of VRC01.

Example 10 HIV Antibody Consensus Sequence

The foregoing experiments defined a class of agonistic anti-CD4bs antibodies, HAADs, that shares IgV_(H) and IgV_(L) consensus sequences including 8 of the contact residues between VRC01 and the HIV spike (FIGS. 3A and B). In five different donors, selected for their high level serologic anti-HIV activity, these antibodies originated from only 2 closely related IgV_(H) and 3 IgV_(L) germline genes that conform to the HAAD consensus: V_(H)1-2 and V_(H)1-46 differ by only 7 amino acids, none of which are part of the consensus (FIG. 3A). Despite extensive somatic hypermutation, the consensus residues were retained in their germline form.

The only exception to the consensus, 8ANC195, differed from the others in a number of ways that suggest that it may have a unique mode of antigen recognition: absence of the Arg in the heavy chain that mimics the critical Arg59_(CD4) and Asp368_(gp120) contact site; unique neutralizing pattern; and inability to facilitate anti-CD4i antibody binding. This antibody is one of two distinct highly active antibodies arising in one patient, lending additional support to the idea that serologic neutralizing activity is combinatorial.
